摘　　要：测定了矫直前后钢轨外形尺寸变化（包括轨头宽度、轨高、钢轨长度），分析了轨高减少的原因。通过试验室模拟，提出了轨高减少的变形机理。The contour size changes of rail before and after straightening,involving width of rail head ,rail height and rail length,were measured.The causes of rail height decrease were analyzed.The deformation mechanism of rail height decrease was put forward by means of laboratory simulation.

关 键 词：钢轨 辊式矫直 轧高变化 矫直
